STEAM-RADIATOR.

SPECIFICATION forming part of Letters Patent No. 310,633, dated January13, 1885. Applicaiion filed December 7, 1883. (No model.)

To all whom it may concern.-

Be it known that we, JUAN B. Anorand JOHN CHAPMAN, of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedSteam-Radiator, of which the following is a full, clear, and ex actdescription.

This invention relates more particularly to that class ofsteam-radiators wherein circulatingpipes are used which communicate attheir ends with upper and lower chambers; and the invention consists ofan improved and simplified method of constructing and connecting thepipes with the chambers, thereby effecting economy in and atthe sametime improving the construction of the radiator.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in

which similar letters of reference indicate corresponding parts in allthe figures.

Figure l is a partly sectional elevation of our new and improvedradiator. Fig. 2 is a detailed transverse sectional elevation of thesame, taken 011 the line :0 x of Fig. 1. Fig. 3 is a detailed plan viewof the lower chamber with the circulating-pipes; and Fig. 4: is an endView of one of the circulating'pipes, Figs. 2, 3, and 4 being enlarged.

A designates the upper and B the lower chamber of the radiator, and C Odesignate the circulating-pipes. The chambers A B are essentiallyduplicates of each other, each being cast with the series of smallopenings (4 in its outer wall to receive the bolts b of the pipes O, andwith the series of larger openings (Z in its inner wall to receive theends of the said circulating'pipes (l. The pipes C are cast alike atboth ends, with the flanges c and diametrical strips or portions 0, andthe said bolts 1) b are by preference cast central to and integral withthe said strips 0, so that no extra fitting is required, save toscrew-thread the outer ends of thesaid bolts to receive the nuts f, theportions 0 being made so as to leave the openings 0 at either side forthe free passage ofthe steam an d water of condensation through thepipes.

If found necessary, or if it is desired to economize weight of materialin making the chambers A B, we shall cast them with theinwardly-projecting enlargements g, surrounding the openings a, and withthe radial bracing-fins g g, reaching from the said enlarge.- ments andfrom the outer wall of the chanr bers to the inner walls of thechambers, to prevent all danger of the outer walls being crushed in whenthe chambers and circulatingpipes G are drawn together by applying thenuts f to the bolts 1).

In assembling the chambers and circulating pipes constituting theradiator, the two sets of packing h and a are used-the former upon theflanges or shoulders c of the pipes O, the latter upon the bolts Z)between the nuts f and outer walls of thechamber-so that when the nuts fare screwed down perfectly steam-tight joints will be formed at all ofthe connections. The steam is admitted to the radiator throughinlet-pipe D, which enters the upper chamber, A, and the products ofcondensation are discharged through the outlet-pipe D, fitted in thelower chamber, B. The chambers A B and pipes G having been put togetherand drawn to place by the nuts f, in order to com plete the radiator,the flange E is attached to the bottom chamber, 13, for supporting theradiator, and the ornamental cover F applied to the top of the chamberA, which finishes the radiator and gives it a nice appearance, andcovers the bolts 1) and nut f.

By constructing the radiator as shown and described it will be seen thatthe number of parts of the radiator are reduced to the minimum, thatirregular shapes are avoided, and that very little fitting of parts isrequired, thusmaking the radiator cheap to manufacture, and the radiatoris at the same time made perfectly practical for its purpose.

Instead of casting the bolts 1) integral with the pipes G, the chambersand pipe might be drawn together by separate bolts and nuts; but thiswould involve extra labor and expenses, and hence the firstdescribedplan is preferred.

WVe are aware that a steam-radiator has been heretofore constructed withloop-pipes having bolts cast therewith between the open ends thereof. Asteam-chamber for said pipes was formed with two round openings for thesteam to pass through to the pipes, and with sleeves through which thebolts passed when the parts were in position; also, that a similarconstruc- IOC tion has been made in which the bolts were separate fromthe loop-pipes, and in which bridges for the bolts were formed in theopen ends of the pipes. \Ve do not desire to claim, broadly, any suchconstructions as of our i11- vention. By our construction a very strongand durable radiator is made. The tubes being single allows of eachbeing separately replaced when broken or injured, and a great saving ofmetal is also afforded by our construction, as nearly the whole of oneface of the '3 steam-chamber is cut away to form the openings d for theseveral tubes, and yet the parts around the openings a are not'weakened,ow-

ing to the fins 9'.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The steamchambers A, formed with the openings a d, and with theenlargements g and radial fins g, for bracing the outer wall of thechamber, in combination with the pipes 0, bridge 0, bolts 1), and nutsf, substantially as and for the purposes set forth.
